About Us

Since 1935, Farmer’s Union Oil of Southern Valley has grown from one small service station to a full-service co-op serving thousands of customers in more than seven counties across North Dakota, South Dakota, and Minnesota.

Today, we provide agronomy services, and we have four Cenex convenience stores that offer a variety of fuels for farms, homes, and vehicles, vehicle maintenance and repair services, home goods, hardware, hot food, snacks, and groceries.

Our team of highly qualified agronomists has over 250 years of joined experience. Combined with our equipment and storage capabilities, we use this experience to solve your agronomy problems professionally, within your timeframe, and before the season ends.
